Concerns about economic slumps and social conflict prompted the businessmen of Columbia to dispatch a delegation of men across the Sierra Nevada Mountains to convince emigrants to come to the Southern Mines by a new trail. The small party sent into the mountains located what they hoped would be a feasible route and then encamped on the Carson River, talking to emigrants and telling them of the wonderful new trail that had just opened up to Tuolumne County. Leading the Columbia delegation was Joseph Morehead.
While most emigrants were suspicious of Morehead's claims of a shorter and easier trail to the mines, the fifty men of the Clark-Skidmore Party from Ohio and Indiana decided to risk the new route. Guided by Morehead, they turned south with their thirteen wagons to follow the Walker River. The early section of the route was much the same as that of the Bidwell Party in 1841, but once they turned into the mountains they were on their own. After about a week they realized they would not make it to Sonora without help, so Morehead and several others set out on horseback to obtain supplies. While they were gone, the other emigrants struggled to bring the wagons as far into the mountains as they could. What they didn't know was that Morehead and his party had become lost. When the relief supplies didn't appear, some of the emigrants began to strike out on foot for the mines. Finally the last group was forced to abandon the wagons and follow the example of their colleagues.
When they reached a valley on the headwaters of the Stanislaus River many were sick and all were hungry. They camped in a valley at the foot of a peak today known as East Flange Rock. It was there that Morehead and the relief train met them, thus giving the location the name of Relief Camp. Morehead's group had eventually found their way to Sonora and Columbia, gathered a pack train of supplies, and had returned up the trail. With the fresh provisions many of the remaining emigrants went back for the wagons and brought them over the mountains without mishap. They were greeted in Columbia with a party in their honor.
Although the press and even the members of the Clark-Skidmore Party praised the new trail, the route would prove to be among the most difficult of the emigrant trails across the Sierra Nevada.
